The history of recording and conserving for maintenance the human's memory from ancient times to modern's has brought about a lot of changing process of the recorded information media with developing in culture, and each society has made important recorded materials in his library as essentially the social apparatus. But most of them that were damaged by factors of the natural disaster, humidity, temperature, light, fungi and insects in the library, and were resulted in deterioration and losing the numerous materials. For removing the inevitable phases repeated, there are studying for counterplan of the fundamental environment factors about preservation, restoration and chemical research of materials in advanced countries, but I get a few researches about protecting the cultural properties. Therefore I research the survey of the actual conditions on 72 university libraries centering around them, and then I have researched the collection rate 81 percent, 58 university libraries. (local : 35, in seoul : 23) As the result of this research, I propose the model of the environment factors of conserving the library materials. 1) To apply the equipment of processing the radiant energy to the new construction and buildings. 2) To remove factors that occur fungi and insects by facilities being controlled relative humility, temperature, and to equip the ventilation arrangement in the library. 3) To shelve all acquired and bound materials after proceeding the vacuum fumigator. 4) Those who want to enter into the library stack were surely taken in sterilzing their hands and shoes, and must put on the gown. 5) To use the vacuum dusting thing (machine) for removing the dust without spreading out the floor of the library at any time. 6) To set up the gas automatic fire extinguisher worked by smoke sensor. 7) To assist the research into the preservation, natures and environment of recorded materials, and to supply financial funds for librarian. 8) To hold regularly the workshop be able to educate the methods of preservation materials by the constant system. (Library Association) 9) To add to responsibilities on certification of preservation materials for librarian. 10) To hold the constant committee system in each library. 11) To keep up with the ideal environment (humidity, temperature, light, ventilation, etc.) of preservation materials in the arrangement room, and to put on the gown.

This study introduced speical characteristics of an epidemiologic study on blood pressure and compared several statistical methods for evaluating the tracking phenomenon of blood pressure for Korean children. While correlation coefficients adjusted for measurement error are commonly used for the evaluation of tracking, it is hard to interpretate the results when correlation functions for lag-difference are not monotonous. McMahan defined a tracking as maintenance of relative rank over time and calculated tracking index usng growth curve model. The tracking index in McMahan's model is complicate to calculate, and it is hard to determine the degree of growth curve parameter. Blomqvist showed the relationship between the rate of change and the initial value. This concept could be extended for the evaluation of tracking. However, it is not so easy to interpretate the estimates in his model when those are non-positive.

In ubiquitous environment a user can be provided with context-aware services based on his or her current location, time, and atmosphere. LBS(Location-Based Services) play an important role for ubiquitous context-aware computing. Because deployment and maintenance of this specialized equipment is costly, many studies have been conducted on positioning using only wireless equipment under a wireless LAN infrastructure. Because a CPS(Cooperative Positioning System) that uses the RSSI (Received Signal Strength Indicator) between mobile equipments is more accurate than beacon based positioning system, it requires great concentration in its applications. This study investigates the relationship between nodes by analyzing a WiPS (Wireless LAN indoor Positioning System), a similar type of CPS, and proposes a improved WiCOPS-d(Wireless Cooperative Positioning System using node density) to increase performance by determining the convergence adjustment factor based on node density.

Since the military servants' rebellion, the society of the Goryeo(高麗) dynasty had been getting into crisis worse and worse until late in it. Late in the 14th century, the society was constantly meeting tension and chaos including decline of the Yuan(元) dynasty, sudden rise of the Ming(明) dynasty and etc. This study is aimed to investigate the idea of justice and theory of governing advocated by Yaeun Jeon Nok Saeng, who lived in such tensed and chaotic era. Under the circumstance that threatened the national power of the Goryeo dynasty in the era where the Yuan dynasty changed to Ming dynasty, his idea of justice was expressed as "Theory for Friendship with Ming and Against Yuan", which was proposed in the aspect of considering the safety and maintenance of the nation and getting back the original national power of a country Goryeo. He thought that you should not make your people bothered by or troubled in their works but you should make them concentrate on their jobs for living to govern them eased. He emphasized that you should focus on stability of people's welfare in gentle ways not bothering your people even a little bit because he thought that the situation of that era looked like a thread bobbin so that it could get naturally and easily twisted if you went in hurry.

Liraglutide (Saxenda^R) is prescribed to induce and sustain weight loss in obese patients. The starting dose of liraglutide is 0.6 mg/day for 1 week, which is increased by 0.6 mg/day every week until the full maintenance dose of 3 mg/day is achieved. Such dose titration is needed to prevent side effects, which primarily include gastrointestinal problems such as nausea, diarrhea, constipation, vomiting, dyspepsia, and abdominal pain. A 35-year-old, reportedly healthy obese man receiving liraglutide treatment for obesity visited the emergency room complaining of generalized weakness and dizziness accompanied by repeated diarrhea and vomiting. He reported over 20 episodes of diarrhea starting the day after liraglutide dose escalation from 1.2 mg/day to 1.8 mg/day. Laboratory findings suggested pre-renal acute kidney injury, including serum creatinine 4.77 mg/dl, blood urea nitrogen (BUN) 37 mg/dl, estimated glomerular filtration rate (eGFR) 15 ml/min/1.73 m², and Fractional excretion of sodium 0.08. After volume repletion therapy, his renal function recovered to a normal range with laboratory values of creatinine 1.08 mg/dl, BUN 14 mg/dl, and eGFR 88 ml/min/1.73 m². This case emphasizes the need for caution when prescribing glucagon-like peptide-1 receptor agonists, including liraglutide, given the risk of serious renal impairments induced by volume depletion and dehydration through severe-grade diarrhea and vomiting.

His paper looks more closely at the Republic of Korea's (ROK) Navy submarine berth-allocation strategies, with the study's results ultimately resulting in the proposition of an integer programming model. Current submarine berth-allocation planning problems include the need for more minimal berth-shifting and general support service failures, as a lack of efficient submarine berth-allocation often leads to submarines unable to receive the support service they need due to the inadequacy of their assigned berths. Currently, the ROK Navy allocates berths by only taking available reserve resources and the full-capacity limits of support services into account. This paper expands upon this strategy, and proposes a model which would allow for submarine berth allocation planning to also take submarine support service scheduling into account, allowing for more efficient and timely submarine servicing. This proposed model in turn minimizes berth shifting, support service failures, and allows for full coordination with the submarine support service request schedule. The construction of this model was carried out through data gathered on the ROK Navy's fleets and forces, allowing for a more nuanced analysis of existing issues with submarine berth-allocation planning.

Due to the car's central role in modern life, the industry has become more fiercely competitive, with each manufacturer doing everything it can to attract buyers with features like plush interiors, comprehensive warranties, and helpful customer service departments. Customers may not have the luxury of buying a new car, so they will have to buy a used car. Nevertheless, in most cases, the customer (car driver) may be deceived about the vehicle information and history and thus will be confused in making his/her decision to purchase. In addition, after all attempts to obtain vehicle information (plate number, model, year of manufacture, number of maintenance times, accidents, etc.), the customer's many attempts may fail. In general, the government records and verifies the information of all cars, even those that pass through their borders. However, there might still be some trouble in obtaining this information. From this standpoint, we will design a website that makes it easier for car drivers, car companies and governments to carry out all the above-mentioned processes. It will also allow users, whether a driver or a car company, to inquire about all vehicle information through detailed and integrated reports on its condition since its entry into the Kingdom of Saudi Arabia until the present time, in addition to information supported by numbers and statistics to ensure the integrity and reliability of the information. This platform will save the trouble of searching for car information for drivers and car companies. It will also help governments keep track of the information of all cars entering and leaving the Kingdom of Saudi Arabia, which will contribute to facilitating the process of viewing the history of any car that has previously entered the Kingdom's borders.

Allan-Herndon-Dudley syndrome (AHDS) is a rare X-linked neurodevelopmental disorder with abnormal thyroid function caused by mutation in the solute carrier family 16 member 2 (SLC16A2) gene. Clinical manifestations of AHDS are global or axial hypotonia, a variety of movement disorders, severe intellectual disability, quadriplegia or spastic diplegia, growth failure, and seizures. A 10-year-old boy visited our hospital with the chief complaint of newly onset generalized tonic seizures with vocalization of weekly to daily frequency. He showed early infantile hypotonia, severe intellectual disability, and frequent respiratory infections. He could not walk independently and was non-verbal. Electroencephalogram revealed generalized slow spike and waves with multifocal spikes and slow background rhythms. His tonic seizures were controlled with more than two anti-seizure medications (ASMs). At 11 years of age, he was evaluated for thyroid function as part of regular screening for ASM maintenance and was found to have abnormal thyroid function. We performed whole exome sequencing for severe global developmental delay, drug-resistant epilepsy, and abnormal thyroid function. The hemizygous c.940C>T (p.Arg314Ter) variant in the SLC16A2 gene (NM_006517.5) was identified and confirmed based on Sanger sequencing. Herein, we describe a case of an AHDS patient with late-onset drug-resistant epilepsy combined with congenital hypotonia, global developmental delay, and abnormal thyroid function results. To the best of our knowledge, this is the oldest adolescent among AHDS cases reported in Korea. In this report, clinical characteristics of a mid-adolescence patient with AHDS were presented.

This is a survey of the reserved book system in the pilot universities in Korea. We have surveyed only 22 university libraries among 29 pilot schools as of 1977, because of the differences in the library users, library organization, library facilities, and library materials between universities and colleges. In 1972, the Korean Ministry of Education developed a reformation plan for their higher education based on the teaching method of curriculum-oriented faculty instead of that of the faculty-oriented curriculum. The former puts emphasis on the cultivation of a student's thinking, creativity, and judgement through self-teaching to do a given assignment. The reserved book system in a college or university library is one of the most important methods necessary to accomplish the above educational aim. The survey used a questionnaire with 50 question on 28 items concerning the various aspects of the reserved book system in 22 pilot universities. the survey result discovered many problems needing correction. The following list describes the measures needed to correct the problems found in the pilot universities. 1. The management of a centralized reserved book system is much more effective and economical than the decentralized reserved book system when a university is located on the same campus. 2. In the university library, an independent reserved book department requires to gain the desired educational aims as compared with the reserved book room controlled by any other department in the library. 3. The reserved book system should not be adopted by all the departments at once but enlarged gradually, for it needs the understanding and support of faculty members and the university itself. 4. As competence is essential to the effective operation of the reserved book room, the university library should not place an unqualified person in charge of the reserved book department. 5. The librarian in charge of the reserved book department is required to do more professional works such as analysis of users, collection and analysis of syllabuses, maintenance of faculty member cooperation, establishment of measures to acquire unavailable materials, and drawing up an effective management plan. However, he is spending most of his time in clerical works, that is, non-professional works. 6. Three to five titles of each reserved book are considered reasonable and required materials should be shelved in proportion to the number of students, that is, one copy per eight or ten students if the materials are allowed to lend for two hours at a time. For the supplementary materials, the library needs to place two or three copies per subject. 7. Professors must select reserved books with care so that they can be used year after year. 8. Few universities are asking professors the number of class students and the date when the reserved material will no longer be needed on reserve. 9. The library should gather all the lists of reserved books from every professor at least three to five months before the courses open, because it takes a long time to obtain foreign materials. 10. It is desirable that the reserved book department should collect the lists and prepare the materials with promptness and consistency. 11. Instead of block buying, it is desirable to purchase reserved books at the time the library gets the reserved book list from the professors. The library should also inform faculty members whether it obtained each reserved book or not before the course open. 12. The library should make a copy of materials if a professor requires to reserve an out-of-print book or partial contents of a book, journal, and thesis. 13. An independent budger for reserved books from the budget for general materials is desired. 14. The shelf arrangement of reserved books by courses or professors under the same department is much more preferable than a classified arrangement. 15. While most of the universities adopted the open shelves system for all the reserved books, it is more effective and economical to take a compromise system, that is, closed shelves for requires materials and open shelves for supplementary materials. 18. Circulation of reserved books needs a different system between required materials and supplementary materials: two or three hours and/or overnight loan for the former and two and/or three days loan for the latter. 17. A reserved book room should be open a long time after class so that students can have sufficient time to use the room. 18. The library must take daily and monthly statistic as well as statistics on every aspect of the reserved book system in order that the library ma decide on policy and management of the reserved book room in collaboration with the university. Furthermore, regular reports on the use of the reserved book room should be made to the president and the executive council by the library to acquire their understanding and cooperation for the reserved book system. 19. Cooperation of faculty members is indispensable to the effective management of the reserved book department and it is desirable to make a committee which will fix various decisions about the system. Whenever the director of the library make his decision, he must consult with his staff in order to involve them earnestly in the operation of the system.

Limb-girdle muscular dystrophy (LGMD) which is characterized by progressive muscle weakening of the hip and shoulder shows both dominant and recessive inheritances with many pathogenic genes including TTN. This study performed to identify genetic causes of a male patient with late onset (45 years old) autosomal recessive LGMD and atrial flutter. By application of the whole exome sequencing, we identified bi-allelic variants of TTN gene in the patient. One allele had a single missense variant of [c.24124G>T (p.V8042F)], while the other allele consisted of three missense variants of [c.29222G>C (p.R9741P) + c.67490A>G (p.H22497R) + c.75376C>T (p.R25126C)]. The p.V8042F allele was transmitted from his mother, while the other haplotype allele was putatively transmitted from his father. His two unaffected sons had only the p.R9741P. These variants have been not reported or rarely reported in the public human genome databases (1,000 Genome, gnomAD, and KRGDB). Most variants were located in the highly conserved immunoglobulin or fibronectin domains and were predicted to be pathogenic by the in silico analyses. The TTN giant protein plays a key role in muscle assembly, force transmission at the Z-line, and maintenance of resting tension in the I-band. In conclusion, we think that these bi-allelic compound heterozygous mutations may play a role as the genetic causes of the LGMD phenotype.
